Angelina Jolie's Texan baby

The couple - who already have four children - have moved into a secluded 270-acre ranch outside the small, rural town of Smallsville while Brad films 'Tree of Life' and are likely to still be there when Angelina gives birth in around four months time.

A source said: "Brad and Angelina love the South. They weren't planning to move to Texas for filming, but Angelina is all for trying something new.

"They were offered several beautiful properties in the town but settled on the ranch because it is set way back from the road and prying eyes."

Brad and Angelina - who have three adopted children, six-year-old Maddox, four-year-old Pax and Zahara, three, as well as a biological daughter, 21-month-old Shiloh - arrived at their new home in February.

One resident said: "I saw two huge vans, loaded with every toy and child-sized car and truck you could imagine."

Meanwhile, the couple have reportedly put their marriage plans on hold following a blazing argument over details of the ceremony.

Brad is keen on a big wedding in New Orleans, where the couple own a property, while Angelina has her heart set on an intimate affair in France, according to America's Star magazine.

Another sticking point is said to be Brad's decision to invite his ex-wife Jennifer Aniston to the nuptials, although he is adamant she will not turn up.
